Error while installing nodeJS mysql package on Windows 7

I am new to nodeJS,

I am trying to install mysql package of nodeJS as

>node

>npm install mysql

and also with

>npm install node-mysql

but getting error as

npm should be run out side of the node repl in your normal shell

so i run the same command in side nodeJS directory in program file

still getting error check images node shell command node-debug.log

This error is indicating that the path referred to in the screenshot above (.../AppData/Roaming/npm) is not available (doesn't exist or isn't accessible by your user).

Can you make sure there is a folder npm at this path:

c:\Users\mayank.bhadauria\appdata\roaming

If not, please create it and then try npm install node-mysql again.
